This invention relates to improvements in wrist watch straps, and particularly to improvements in leather wrist watch straps.

One of the principal objects of the present invention is to provide a leather Wrist watch strap in which the forces and strains are counteracted to provide a strap having greater strength and durability.

Another object of this invention is the provision of a leather wrist watch strap composed of the usual separable sections, and each section in turn being formed from a plurality of pieces or parts whereby an infinite number of designs may result while utilizing the general make-up or structure of the strap.

A further object of the invention is to provide an improved strap capable of modification upon the structure as disclosed in the United States Patent No. 2,035,671, issued to Albert H. Sauer, Jr., on March 31, 1936.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof, and it is to be understood that any modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

As was noted above, this invention pertains to improvements in the construction of a leather wrist watch strap in which the strains and forces on said strap are better compensated for, and to provide an improved construction whereby a greater number of designs in wrist watch straps may be made while utilizing the principles of construction as set forth hereinafter. At the same time this invention discloses improved constructional features and details over the United States Patent No. 2,035,671 of Albert H. Sauer, J r., which issued March 31, 1936.

Specifically referring to the drawings, each of the modified straps there illustrated comprises a tongue section indicated in general by the reference numeral 15 and a buckle section indicated in general by the reference numeral I6. The said sections each have their inner ends connected to a wrist watch IT. The tongue section as seen in Figs. 1 to 4 inclusive comprises an inner part I8, a center or ornamental part 19, and the tongue part 20.

As seen in Fig. 3, the inner part l8 comprises a piece of leather folded on itself to provide at the ends thereof loops or openings 21 and 22, the folds being secured to one another by means of a line of stitches 23. The loop or opening 2| is adapted to'receive the wrist watch attaching pin 24, while the other loop 22 is utilized for attaching the center ornamental part to the end part. This central ornamental part 19 may be made up of one or more pieces, which as shown in Fig. 1 comprises three separate pieces. These pieces as shown in Fig. 3 are a ring 25 formed of a leather thong such as more fully illustrated and de- 4 scribed in the co-pending application of Albert Herman Sauer, Jr., Serial No. 759,539, now Patent No. 2,035,672, issued March 31, 1936, for Article of manufacture and the method of making, same which was filed December 28, 1934. 50 This leather thong has its ends abutting one another and secured in this position by means of a metal clip or tie 26. This ring 25 has a portion thereof disposed in the opening or loop 22 of the watch attaching part l8. The ring 25 has an 55 additional portion thereof, and preferably including the metal fastening clip 25, disposed in an opening or loop 21 of the connector 28 of the central ornamental section It. The connector 28, similar to the watch attaching part [8, is formed of a single piece of leather folded on itself to provide the aforementioned loop or opening 21 and a second loop or opening 29, the folds of the connecting section 28 being secured in position by a line of stitching 35. Received in the loop or opening 29 is a portion of a second ring 3lwhich is similar in all respects to the ring 25 and above described. A second portion of the ring 3| is received in a loop or opening 32 formed at the inner end of the tongue part 25. This tongue 20 is formed of a single piece of material folded on itself with the ends thereof overlapping one another and secured by a line of stitching 33. It will be noted from the drawings that the overlapping of the ends of the strip which forms the tongue is adjacent to the loop or opening 32, wherefore the major portion of the tongue part is of uniform thickness and devoid of folds or bumps. The major portion of the tongue folds are cemented to one another so as to maintain same in a fixed desired position, and this tongue portion is provided with a series of apertures or holes 34 to receive the catch of the buckle.

The second section [-6 of the strap has its parts illustrated in perspective in Fig. 4. As there shown, these parts consist of an inner watch attaching part 35 which is similar in all respects to the watch attaching part it. This watch attaching part 35 is connected with the watch I! in the same manner that the watch attaching part 23 is connected therewith, and is connected with a central ornamental part composed of rings 35- and 31, connected to one another by the connecting member 38, which are similar in construction to the rings 25 and 31 and their connecting member 28. The ring 31 is adapted to havea portion thereof received in a loop or opening 39 formed at one end of the buckle supporting part 48. This buckle supporting part 45, similar to the tongue part 20, is formed of a single strip of leather folded on itself to provide the loop 39 at one end thereof, and a second loop 4! at itsother end. It will be noted that the ends of the strip overlap one another adjacent'to the loop 40' and are secured by means of stitching 42. The 'loop 39 at the other end is likewise permanently formed by means of a line of stitching 43. One end of the leather strip forming the buckle part 45 adjacent to the line of stitching 42 is utilized to form an elongated loop 44, see Fig. 2, receiving the lower surface of the tongue retaining loop 45, the loop 44 being permanently formed by means of a line of stitching 45. It should be noted at this time that the body portion of the leather between the lines of stitching 43 and 42 are cemented to one another to retain same in position.

Received in the outermost loop 4| of the buckle part 40 is the pin 46' for the buckle frame 4'! and the buckle clasp 48. The inner end of the buckle clasp 48 is disposed in a cut-away or recessed portion 49 formed in the buckle part 40.

From the foregoing it will be seen that each of the several parts of each section of the watch strap is substantially independently formed and simply hooked or threaded through each other to effect a complete connection one with the other, instead of connecting these parts directly by means of stitches or the like. Due to this particular arrangement the strains and stresses are taken primarily by'the fibers of the leather 'to the watch-attaching parts l8 and 35.

of the strap instead of by stitches which connect the several parts to one another.

In the modified strap illustrated in Figs. to 8 inclusive, the tongue part 50 and buckle part 5| are respectively sewed or stitched to the ornamental center sections instead of looped therewith. This construction is clearly illustrated in Fig. 7.

As seen in Fig. 7, use is made of a watch attaching part 52 which is similar in all respects Instead of the watch attaching part 52' receiving therein a portion of an ornamental ring, it instead receives therein the body portion of a loop 53 which has its ends 54 and 55 projecting free therefrom, the free ends 54 and 55 being spaced by an ornamental. metallic member 56 located immediately at the base of the loop 53. The free ends 54 and 55 are disposed between the free gaping ends 51 and 58 of the tongue section 50. This tongue section 50 is similar to the one illustrated in the above-noted co-pending application Serial No. 752,494. This tongue part 50, similar to the tongue part 25, is formed of a single piece of leather with the body portion overlapped and secured to one another, and with the ends free and gaping as illustrated at 51 and 58. After the ends 54 and 55 of the connecting thongs are placed between the gaping ends 51 and 58, the parts are placed on top-of one another and secured in position by means of stitching 59, see Fig. 5.

The buckle section of the strap of Figs. 5 and 6 is similar in construction to the tongue section just described and comprises a watch attaching part 5!] and a central ornamental connecting part 6| which are respectively similar to the parts of the tongue section just described. The free ends of the connecting part 6| are disposed between the free and gaping ends 62 and 63 of the buckle part 64 which is formed of a single piece of material folded on itself to provide a loop or opening 65 at one end thereof, the parts being secured in position by a line of stitching 65. Immediately behind the stitching 56 the folds of the buckle part 5| are separated to provide an opening for one side of the tongue loop 61', this tongue loop opening being permanently provided by means of a line of stitching 68. The free and gaping ends 62 and 63 of the buckle part 5| are secured to the free ends of the connecting section Bl by means of stitches 69.

From the foregoing it will be noted that the strap of Figs. 5 to 8 inclusive is composed of certain parts of the strap illustrated in Figs. 3 and 4, and of certain parts illustrated in the above-mentioned co-pending application. With this construction additional designs may be provided over and above. the designs as may be effected by either the construction in Figs. 1 to 4 inclusive or the construction of the co-pending application. In Figs. 9 to 12 inclusive there is illustrated a further modification in the construction details of a wrist watch strap which strap again. combines parts or constructional features of the strap illustrated in Figs. 1 to 8 inclusive, and in the above referred to co-pending application. As will be noted from Figs. 9 and the buckle part Ill and the tongue part H are identical with the buckle part 40 and tongue part 20 of Figs. 1 and 2, while the connecting ornamental sections 12 and 13 are substantially identical with the connectingsections illustrated. in Figs. 5 and 6. I4 and 15, however, are different from the other The inner watch attaching parts watch attaching parts illustrated in the drawings but are substantially identical with that illustrated in the oo-pending application Serial No. 752,494. As shown in Figs. 11 and 12, each of these watch attaching parts is formed of a single piece of leather folded on itself to provide the watch pin bar loops l6 and 11 with the ends free and gaping as shown at I3 and 79. The free and gaping ends 18 and 19 receive between them the free projecting ends of the ornamental connecting sections 12 and 13, and these parts are secured to one another by the stitching 80.

By comparison of Figs. 5 and 9 it will be noted that the strap designs there illustrated are substantially the reverse of one another, having the loops 53 in one instance adjacent the tongue and buckle sections, and in the other instance adjacent the wrist watch.

From the foregoing it will now be noted that there has been provided by this invention a technique of Wrist watch manufacture which meets all of the requirements for a comfortable wrist watch strap such as provided by leather or other flexible material, while, at the same time, providing a structure which will produce an infinite variety of strap designs.
